It looks like you didn't have a great company hosting you. I have never heard of unpaid OT during a retreat.
I run this small company and I take a lot of effort to find the right budget to give a good experience for my team. If I give a bad experience during the 3-4 days, then why would they come back recharged to the office?
Organizing a retreat takes significant time and money from the company. If someone is using that just to force a few team members to work unpaid, they really don't see the bigger picture. Get out of the place asap :)
